This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X70U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X70U in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 70mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X70U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70U
The AirTAC MAL25X70U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 70mm stroke. It delivers 245N push and 206N pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X70U, matching the bore, stroke, output, G1/8 port, and U flat-end rear cover. The legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
This specific SKU lacks a built-in magnet, so it cannot accept position sensors. The piston relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide. A carbon-steel rod with 20um hard-chrome plating drives the load, while end-of-travel deceleration is handled by a fixed rubber bumper rather than an adjustable cushion.

| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X70U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The MBL25X70U produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70U Is Used
PCB Depaneling Router
Pushes a 245N pin to clamp motherboards during routing, using the 70mm stroke to clear the spindle before unloading.
Carton Flap Folder
Actuates a 25mm bore arm at 206N pull to tuck minor flaps on small packaging lines, fitting neatly into tight conveyor gaps.
Lab Tube Capper
Drives a 10mm rod downward to press and spin caps onto vials, relying on the fixed rubber bumper to soften the bottoming impact.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70U with MBL25X70U
To replace the MAL25X70U, order the MBL25X70U. Confirm the 25mm bore, 70mm stroke, G1/8 port, and default PT tapered thread. Because this SKU has no -S magnet, it cannot support a sensor; if you need position detection, step up to an MBL25X70US and upgrade to the current CMSG, DMSG, or EMSG switch family (the older CS1-M/DS1-M sensors are for the legacy line). If your application requires adjustable air cushioning instead of the standard fixed rubber bumper, specify the MBLC25X70U.
For sizing flexibility, stepping down to a 20mm bore yields 157N push at 0.5 MPa, while stepping up to a 32mm bore provides 402N push. Note that a plain cylinder does not hold its position if air pressure drops; add an external rod lock or pilot-operated check valve for suspended loads. At 70mm stroke, side-load risk is minimal, but ensure the rigid U flat-end back cover is squarely aligned to avoid binding the 10mm rod.
Upgrade checklist
- ✓ Order the MBL25X70U (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the MBL25X70U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70U FAQ
Yes, the MAL25X70U is discontinued. The exact drop-in replacement is the MBL25X70U, which matches the 25mm bore, 70mm stroke, G1/8 port, and U flat-end mounting. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but maintains identical output force.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa. This specific U flat-end SKU has no magnet, so it cannot use CS1-M or DS1-M sensors.
